Dometic ndr1292 not working correctly

Hi got a new to us 2007 gulfstream crescendo dp and Recently on a trip we found that the fridge gets to about 38 degrees when on setting 3 and the freezer gets to about 15 degrees when on setting 3. When we select setting 4 or 5 on the panel for colder operation the fridge and freezer actually get warmer?? the fridge is in a slide out so I installed 3 computer case fans at the bottom facing up that are on anytime the fridge is on, there are 2 more muffin fans at the top the pull air up and exhaust it out and they do come on when the temp requires it. The drain tube is correct and not allowing air into fridge. The seals are nice and tight with the dollar bill test....This is happening regardless of being plugged in or on propane. Anyone have any ideas?

    If it gets warmer on 4-5 try it on 1-2 it may get colder. Previous owner may have worked on it and may have suffered dyslexia.

    Have you tried removing it and standing it upside down for a day and then another day upright before you put heat on it again?

    That may just work. It also may not.

    I have learned through the years that the half-life of RV absorption refrigerators is about 7 years. If it is dead, seek out one of the Amish guys that rebuild the cooling units.
